Improved arrangement in a polygonal plate upside-timiento excavation and support land

摘要

1.Disposición perfected in a polygonal plate for lining excavations and maintenance of land, type of corrugated plates obtained by stamping a metal sheet, wherein the profile whose directrix is ​​a polygonal line formed by devoid trapezoid its larger base and linked segment longitudinally and with equal configurations alternating transversally presents in extreme flat areas elongated concave deformations made in the configuration process itself achieving such deformations increase the rigidity of the plate in these flat areas particularly susceptible alteration by the efforts of the land, and that interest continue to maintain the polygonal guideline with which they were designed, while modifying the smooth surface finish, favor the flow of the mass deformations and concrete adhesion when used as the plate and I ncofrado lost. 2.Disposición perfected in a polygonal plate for lining excavations and maintenance of land.
